2 networks, one hub please help.

[thunderninja]

I have an office with 2 networks with 2 IP addresses. The setup is as follows:
Internet to fiber modem to switch, switch to router 1 and router 2, router 1 to hub, hub to patch panel that fans out to wall panels in 6 offices. Router 2 used to have a long patch cable plugged directly into a computer in the office adjacent to the network closet, so only that computer was on a different network than everyone else in the office. The user of that computer now has to move to a corner office 70 ft away. We thought the solution would be to plug router 2 into the hub port corresponding to the wall panel in the corner office instead of directly into the computer but there is no connectivity when we do this.

A solution would be to buy an extremely long patch cable and rope it through the ceiling and drop it down into the corner office or buy wireless router to replace router 2 and attach a wireless dongle to the old computer, but both of those solutions are not very practical.

Is there any reason the first solution would not work? The problem is that router 2 has been known to stop working and require multiple resets so if there is no reason the first solution shouldn't work, then it could just be the spotty router. Sorry, I am not a tech person at all, just the only person under age 70 in a real estate office so I am left with tasks like this by default. If anyone can help, greatly appreciated.

A way that will work if functionality is your primary concern an security is secondary. On router 2 turn off DHCP. Assign the LAN IP something within the range of router1. IE say you use 192.168.100.x for your network and router 1 is 192.168.100.1 assigned router 2 something like 192.168.100.253. Now assign the pc that is to use router 2 a static ip in the same range say 192.168.100.252 and set its dns and gateway to 192.168.100.253. You may have to set the DNS on the PC to a real dns or use 8.8.8.8 or 4.2.2.2. Finally exclude 192.168.100.252 and 192.168.100.253 from router1 dhcp range so it does not attempt to assign these to another machine.
You would plug everything into the hub.

This is the same solution to the question of how do i run 2 routers/isp on the same network and share them. The security risk is anyone that know how to change the gateway on their machine can use either router.

If you need to do it securely i am going to say a long ethernet cable is going to be the simplest,cheapest to accomplish if that is a option. To do it correctly you would need a switch/hub that can do vlans which tends to not be cheap.

Now i am assuming that when you plug this pc into the wall jack when it is connected to the hub it does work correctly it is just on the wrong router. If not you have something wrong with ip configuration on the pc

I appreciate your help. The first setup was correct for our purposes, the router is just bad. We don't require sharing between the two networks. After I unplugged and plugged the router multiple times it started working. Time for a new one.
